Title: Prevent `Uncaught TypeError: Cannot call method 'disable' of undefined`

When i pulled the latest code into my 2.1 project, i ran into the mentioned error whenever navigating away from a panel that doesn't use scrolling.

This is suggestion for a quick fix for the jscroller part, tested in chrome and on Galaxy Mini 2 (2.3.6).
